   This returns the current database profiling level.
  </p>
  <p class="para">
   The database profiler tracks query execution times.  If you turn it on (say,
   using <span class="function"><a href="mongodb.setprofilinglevel.html" class="function">MongoDB::setProfilingLevel()</a></span> or the shell), you can
   see how many queries took longer than a given number of milliseconds or the
   timing for all queries.
  </p>
  <p class="para">
   Note that profiling slows down queries, so it is better to use in development
   or testing than in a time-sensitive application.
